摘要
The catalytic performance of MnOx-CeO2 for the simultaneous NOx reduction and chlorobenzene (CB) oxidation was investigated. The MnOx(0.4)-CeO2 solid composition exhibited excellent catalytic activity due to the formation of MnyCe1-yO2-delta solid solution and the good balance between redox properties and surface acidity compared to pure ceria. The presence of CB improved both the NOx conversion and N-2 selectivity in the range of 200-300 degrees C. Furthermore, the activity temperature window for NOx reduction was broadened when CB was introduced into the flue gas, and the CB oxidation ability was also enhanced in the presence of O-2 and NH3/NO.
